Thread: Inaccurate Cartridges

So yesterday thanks to kiwi greg I had a bit of schooling on the 22 terminator and its lineage.
Delving further I encountered a whole raft of cartridges described as being known for their superb accuracy. This got me thinking has anyone heard of one described as being superbly innacurate?
I know most of the influencing factors are bullet construction and design, rifling twist rate, barrel construction, bore tolerance, condition and concentricity, action type and rigidity etc and of course the "nut behind the butt"
I know we all have personal favourites and pet hates, mention 270 or 243 here and see what happens but all that aside assuming all of these thing are sorted are there really any cartridges that would have trouble hitting a flock of barns at 10 paces?

i cant say i have heard of a inherently inaccurate cartridge, especially if you bring the times they were developed in as a factor, a .45/70 isnt going to compete with a 6mm PPC etc . . . would think the quality of the 3 Bs are more important, Barrel, Bullet & Bedding for most applications . . . . something to think about today as i drive . . cheers

Never seen a half Moa .303

A P14 will do it with target ammo. Mk 7 service was fit for purpose and produced at astronomical rates.
In this case the bad reputation is mostly due to the state of the rifles being used.

Modern shooters a spoilt back in the 50' 60's and 70's any rifle that could shoot 4 MOA was considered adequate for general hunting,
there were some accurate .303's built on P14 actions what stuffed them up was shooting cordite loaded military surplus ammo through them
only took a couple of those to start eroding the throat, if you find a new .303 barrel don't shoot military ammo through it ,
My old 2 groove No4 would shoot 1.5 MOA with the right bullet even though it had been shot with surplus ammo,
nothing wrong with the cartridge just the use of the wrong powder

What's the better groove barrel to go for in the 303?.... I see some nice spotters come up for sale for not much.

Sporters

2 groove rifles are not necessarily less accurate than the 5 groove ones but they seem to do better with flat base bullets

A new Fulton regulated No4 was good for .75moa with MkVII issue ball back in the fifties. One could probably have got better with hand loading

22 Magnum comes to mind. Not known for good accuracy, compared to it's little brother anyway.

I have a Marlin 25NM in .22WM and it with Hornady ammo shots half moa with ease even with me behind the trigger.

It has that reputation but I don't know if its actually justified or not.

I've only had one of them (Savage 93G), it generally shot around 1-1.5" at 100yds depending what I fed it. Less variety of ammo options than 22LR if you get a fussy one I suppose.
